NOZZLE.

SPECIFICATION forming part of Letters Patent No. 573,721, dated December22, 1896.

Application filed October 5, 1895.

To all whom it may concern..-

Be it known that we, WILLIAM A. SWIFT and WILLIAM W. STEWART, residentsof Columbus, in the county of Muscogee and State of Georgia, haveinvented certain new and useful Improvements in Nozzles; and we dohereby declare the following to .be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

Our invention relates to an improvement in nozzles, the object of theinvention being to produce a nozzle by means of which the fireman can beprotected from excessive heat.

A further object is to so construct a nozzle that a spray of water canbe made to flow from the same in rear of the tip through which thestraight stream passes.

A further object is to produce a nozzle by means of which a solid streamand a spray may be made to flow therefrom simultaneously, or either astream or a sprayseparately.

A further object is to produce a nozzle which may be used as a lawn orstreet sprinkler by setting the nozzle in a portable stand or with thenozzle attached to a hose and throwing the water at any place which maybe desired.

A further object is to produce a spray in the rear of the tip, and bychanging the tip having solid outlet to one having closed per- I foratedend to form a combination straight and lateral spray, the object beingto use both outlets for sprays when fighting fire at close range, thuscovering large areas.

A further object is to make the tips for different-sized outlets for thewater, say from one-half inch to one and one-half or two inches indiameter, without changing any other part of the nozzle.

With these objects in view the invention consists in certain novelfeatures of construction and combinations and arrangements of parts, ashereinafter set forth, and pointed out in the claims.

In the accompanying drawings, Figure l is a sectional view illustratingan embodiment of our invention. Figs. 2 and 3 are detail views.

A represents a conical pipe or nozzle pro- .posed nearly parallel withthe flange 1.

Serial No. 564,770. (No model.)

vided at its larger end with internal screwthreads at for the receptionof the coupling of a hose, and at its smaller end said pipe or nozzle isprovided with external screw-threads b for the reception of thenozzle-tip or outlet 55.

c. The tip or outlet 0 is made at its rear end with an annular outwardlyand slightly forwardly projecting flange 1, the function of which willbe presently fully explained, or

said flange might be made to project atright angles from the tip.

At a point between its ends the pipe or nozzle A is provided withexternal screw-threads cl, with which screw-threads e at the rear end ofa shell B mesh, said shell being made to inclose a portion of the pipeor nozzle A and form a chamberf between itself and said pipe or nozzle.The forward end of the shell B is madeof greater internal diameter thanthe external diameter of the pipe or nozzle A, so

as to form a duct or channel g, which communicates at its rear end withthe chamber f, and the extreme forward end of the shell is made with anannular flaring flange '5, disaunular outlet-passage 2 is thus formedbetween the flanges 1 and t'. The flange i is slightly curved andprojects somewhat beyond the flange 1.

The pipe or nozzle A is made with a series of elongated openings 3,(preferably four in number,) through which water will pass from saidpipe or nozzle into the chamherf, and from thence through the annularchannel or duct g to the annular outlet 2, from which it will be emittedin the form of a spray similar in shape to an umbrella. v

The nozzle will preferably be provided at a point forwardly of theopening 3 with a valve at, by means of which the flow of water to thetip or outlet 0' can be stopped if desired, and said tip may be madeopen for a solid stream or enlarged and perforated fora spray.

From the construction and arrangement of 9 3 parts above described itwill be seen that a solid stream of water can be made to flow throughthe outlet 0, if open outlet is used, or spray, if a perforated tip,Fig. 3, be used, and

simultaneously a spray will be emitted in rear [00 of the outlet 0. Thisspray will protect the fireman using the nozzle from the excessive heatof the fire.

By means of my improvement a solid stream can be made to flow from thenozzle and at the same time a considerable area in proximity to 1 thefireman can be wet without the necessity of diverting the mainstreamfrom the outlet 0.

If desired, the nozzle can be used without the spray by turning theshell B so as to cause the forward end thereof to bear against the.

rear of the tip 0 and thus close the annular outlet 2, or the spraycould be used independently of the main stream by merely closing thevalve at. The solid stream and spray can thus be used simultaneously oreither one without the other, as desired.

By making the flange 'i curved and wider than the flange 1 it will beseen that by causing the flange 2' to approach comparatively close tothe flange 1 the spray can be made to flow straight ahead, orapproximatelyso. By movin g the flange 2' rearwardly, so as to enlargethe chamber or outlet 2, the spray will flow laterally, practicallycoincident with the rear face of the flange 1. Instead of making theflanged integral with the shell B, as shown in Fig. 1, it maybe made ona sleeve 1', adapted to screw on the forward end of the shell B, asshown in Fig. 2.

ater might be conveyed to the spray in other ways than above described,and various slight changes might be made in the details of constructionof our invention without departing from the spirit thereof or limitingits scope, and hence we do not wish to limit ourselves to the precisedetails of construction 'herein set forth; but,

Having fully described our invention, what we claim as new, and desireto secure by Letters Patent, is

1. In a nozzle, the combination with a pipe or nozzle having adeflecting annular flange which extends outwardly at an angle thereto'whereby to deflect water coming into contact therewith outwardly, of anadjustable ring or collar back of said flange between which and theflange a passage for water is formed, said ring or collar being ofgreater diameter at its outer end than the flange and extendingforwardly at its extreme outer endwhereby to turn the flow of water fromits outward direction to a straight forward course or any intermediateangle between a straight forward course and the outward lateraldirection induced by the annular flange, and means for maintaining acontinuous flow of water from the supply to both' apertures of thenozzle, substantially as set forth.

2. In a nozzle, the combination with a pipe or nozzle having ascrew-thread formed thereon at or near its outer end, and anoutwardlydeflecting annular flange screwed on this thread, of anadjustable annular ring or collar having a greater diameter at its outerend than the flange and projecting forwardly at its outer end whereby tochange the direction of the spray passing between the flange and ring orcollar from a lateral direction to a straight forward course or to anintermediate angle between the outward and forward direction, and meansfor maintaining a continuous flow of water from the supply to bothapertures of the nozzle, substantially as set forth.

In a nozzle, the combination with a pipe or nozzle having ascrew-threaded exterior, a

shell surrounding the pipe or nozzle and screwed thereon whereby anannular space is formed between them, said pipe or nozzle havin gcommunicating openings for the passage of water therefrom into the spacebetween the shell and pipe or nozzle, of an outwardly-projecting flangeon the outer end of the pipe or nozzle, and a ring or collar screwed onthe end of the outer shell, said ring or collar being of greaterdiameter at its outer end than the flange and extending forwardly todeflect the water turned laterally by the flange to difierent angles toa straight forward direction and means for maintaining a continuous flowof water from the supply to both apertures of the nozzle, substantiallyas set forth.

In testimony whereof we have signed this specification in the presenceof two subscribing witnesses.
